VALERO ENERGY CORPORATION

4.350% Senior Notes due 2028

A single series of Securities is hereby established pursuant to Section 301 of the Indenture dated as of March 10, 2015 (the “Indenture”), between Valero Energy Corporation, a Delaware corporation (the “Company”), and U.S. Bank National Association, as Trustee (in such capacity, the “Trustee”), as follows (capitalized terms used and not defined herein shall have the meanings assigned to them in the Indenture, and all references herein to a Section shall refer to the corresponding Section in the Indenture):

1. The title of the 4.350% Senior Notes due 2028 shall be “4.350% Notes due 2028” (the “Notes”).

2. The initial limit upon the aggregate principal amount of the Notes that may be authenticated and delivered under the Indenture (except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 304, 305, 306, 906 or 1207) is $750,000,000, provided, however, that the authorized aggregate principal amount of the Notes may be increased above such amount by a Board Resolution to such effect.

3. The Notes shall be initially issued as Registered Securities in the form of one or more global securities under the Indenture. The Depository Trust Company is hereby designated as the Depository for these global Securities under the Indenture.

As long as any Note is in global form, then, notwithstanding clause (11) of Section 301 and the provisions of Section 302, any such global Note shall represent such of the outstanding Notes as shall be specified therein and may provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced to reflect exchanges or redemptions. Any endorsement of a global Note to reflect the amount, or any increase or decrease in the amount, of outstanding Notes represented thereby shall be made by the Trustee in such manner and upon instructions given by such Person or Persons as shall be specified in such Note or in a Company Order to be delivered to the Trustee pursuant to Section 303. Subject to the provisions of Section 303 and, if applicable Section 304, the Trustee shall deliver and redeliver any Note in permanent global form in the manner and upon instructions given by the Person or Persons specified in such Note or in the applicable Company Order. With respect to Notes that are represented by a global Note, the Company authorizes the execution and delivery by the Trustee of a letter of representations or other similar agreement or instrument in the form customarily provided for by the Depository appointed with respect to such global Note. Any global Note may be deposited with the Depository or its nominee, or may remain in the custody of the Trustee pursuant to a FAST Balance Certificate Agreement or similar agreement between the Trustee and the Depository. If a Company Order has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement or delivery or redelivery of a Note in global form shall be in writing but need not comply with Section 102 and need not be accompanied by an Opinion of Counsel.

Members of, or participants in, the Depository (“Agent Members”) shall have no rights under the Indenture with respect to any global Note held on their behalf by the Depository, or the Trustee as its custodian, or under such global Note and the Depository may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such global Note for all purposes whatsoever. Notwithstanding the foregoing, (i) the registered holder of a global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through an Agent Member, to take any action that a Holder is entitled to take under the Indenture or the Notes and (ii) nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by the Depository or shall impair, as between the Depository and its Agent Members, the operation of customary practices governing the exercise of the rights of a beneficial owner of any Note.

Notwithstanding Section 305, and except as otherwise provided pursuant to Section 301, transfers of a global Note shall be limited to transfers of such global Note in whole but not in part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in a global Note may be transferred in accordance with the rules and procedures of the Depository. In all other respects, Notes shall be transferred to all beneficial owners in exchange for their beneficial interest in a global Security solely as expressly provided in Section 305.

In connection with any transfer of a portion of the beneficial interest in a global Note to beneficial owners pursuant hereto and Section 305, the Security Registrar shall reflect on its books and records the date and a decrease in the principal amount of the global Note in an amount equal to the principal amount of the beneficial interest in the global Note to be transferred, and the Company shall execute, and the Trustee upon receipt of a Company Order for the authentication and delivery of Notes shall authenticate and deliver, one or more Notes of like tenor and amount.

1

In connection with the transfer of an entire global Note to beneficial owners pursuant hereto and Section 305, the global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depository in exchange for its beneficial interest in the global Note, an equal aggregate principal amount of Notes of authorized denominations.

Neither the Company nor the Trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, Notes by the Depository, or for maintaining, supervising or reviewing any records of the Depository relating to the Notes. Neither the Company nor the Trustee shall be liable for any delay by the related global Note Holder or the Depository in identifying the beneficial owners, and each such Person may conclusively rely on, and shall be protected in relying on, instructions from such global Note Holder or the Depository for all purposes (including with respect to the registration and delivery, and the principal amount, of the Notes to be issued).

Notwithstanding the provisions of Sections 201 and 307, unless otherwise specified as contemplated by Section 301, payment of principal of, premium (if any) or interest on any global Note shall be made to the Person or Persons specified in such global Note.

5. The date on which the principal of the Notes are payable shall be June 1, 2028.

The date from which interest shall accrue for the Notes shall be June 1, 2018. The Interest Payment Dates on which interest on the Notes shall be payable are June 1 and December 1, commencing December 1, 2018. Interest on the Notes shall be payable to the persons in whose name the Notes are registered at the close of business on the Regular Record Date for such interest payment, except in the case of default interest, which will be payable as provided in the Indenture. The Regular Record Date for the interest payable on the Notes on any Interest Payment Date shall be the May 15 and November 15, as the case may be, immediately preceding such Interest Payment Date. No Additional Amounts shall be payable with respect to the Notes.

If appropriate wire transfer instructions have been received by the Trustee, not later than five Business Days prior to the record date for an applicable Interest Payment Date, then payments in respect of the Notes evidenced by a global Security (including principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by the Holder of such global Note. In all other cases, payment of interest on the Notes may be made at the option of the Company by check mailed to the address of the person entitled thereto as such address shall appear in the Security Register.

8. The Notes will be redeemable at any time and from time to time prior to March 1, 2028, in whole or in part, at the option of the Company, at a redemption price equal to the greater of (i) 100% of the principal amount of such Notes, and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the date of redemption) calculated as if the maturity date of the Notes was March 1, 2028, discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate (as defined below) plus 20 basis points, as calculated by an Independent Investment Banker (as defined below) plus, in each case, accrued and unpaid interest thereon to the date of redemption; provided that the principal amount of a Security outstanding after redemption in part shall be $2,000 or an integral multiple of $1,000 in excess thereof.

On or after March 1, 2028, the Notes will be redeemable at any time, in whole or in part, at the option of the Company, at a redemption price equal to 100% of the principal amount of such Notes, plus accrued and unpaid interest to, but not including, the date of redemption.

2

published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such date of redemption. The Adjusted Treasury Rate shall be calculated on the third Business Day preceding the date of redemption.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Notes (assuming, for this purpose, that the Notes matured on March 1, 2028) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes (assuming, for this purpose, that the Notes matured on March 1, 2028).

“Comparable Treasury Price” means, with respect to any date of redemption, (i) the average of five Reference Treasury Dealer Quotations for such date of redemption, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company to act as the independent investment banker from time to time.

“Reference Treasury Dealers” means (i) Merrill Lynch, Pierce, Fenner & Smith Incorporated, J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC, and Wells Fargo Securities, LLC or their respective successors; provided that, if any of the foregoing shall cease to be a primary U.S. Government securities dealer (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer; and (ii) any other Primary Treasury Dealer selected by the Company.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any date of redemption, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such date of redemption.

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the date of redemption to each Holder of the Notes to be redeemed. Unless the Company defaults in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on the Notes or portions thereof called for redemption.

9. The Notes shall not be entitled to the benefit of any sinking fund, any optional repurchase or redemption right in favor of any holder thereof or other mandatory repurchase or redemption provisions.

10. The Notes shall be in substantially the form of Attachment A hereto (the “Form of Note”).

11. Each Note that is a global Security shall bear the legend set forth on the face of the Form of Note.

A supplemental indenture that changes or eliminates any covenant or other provision of the Indenture which has expressly been included solely for the benefit of one or more particular series of Debt Securities under the Indenture, or which modifies the rights of the Holders of Debt Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the Indenture of the Holders of Debt Securities of any other series.

9. Defaults and Remedies. Events of Default are defined in the Indenture and generally include: (i) failure to pay principal of or any premium on any Security when due and payable; (ii) failure to pay any interest on any Security when due and payable, and the continuation of the default for 30 days; (iii) failure to perform any other covenant, or breach of any warranty, of the Company in the Indenture, continued for 60 days after written notice is given or received as provided in the Indenture; and (iv) certain events of bankruptcy, insolvency or reorganization.

At any time after a declaration or

A-8

occurrence of acceleration with respect to the Securities has been made, but before a judgment or decree based on acceleration has been obtained, the Event of Default giving rise to such declaration of acceleration shall, under certain circumstances, be deemed to have been waived, and such declaration and its consequences shall be deemed to have been rescinded and annulled.

Holders may not enforce the Indenture or the Securities except as provided in the Indenture.

The Company must furnish an annual compliance certificate to the Trustee.

10. Discharge Prior to Maturity. The Indenture with respect to the Securities shall be discharged and canceled upon the payment of all Securities and, as provided in the Indenture, shall be discharged except for certain obligations upon the irrevocable deposit with the Trustee of funds sufficient for such payment.

11. Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee.

12. Authentication. This Security shall not be valid until authenticated by the manual signature of an authorized signer of the Trustee.
